1. Field of the Invention
The present invention relates to a socket connector, and more particularly to a ZIF (zero-insertion-force) connector having a base detachably assembled with a metal frame for easily facilitating installation of the base onto a printed circuit board.
2. Description of the Related Art
The IC packages are more and more popular in the computer industry. As well known, the IC package is commonly connected to a mother board through a socket connector which is directly mountably soldered on the mother board. Taiwan Patent Issued Number 470224 discloses a socket connector including a base, a cover slidably mounted to the base and a lever including an actuation handle and a cam portion joined with each other. The cam portion is received between the base and the cover, and the handle is exposed to one side of the base. When the handle is in a horizontal position, conductive pins of the IC package loaded onto the cover will engage with conductive means of the socket connector and the socket connector is in a closed state. After the lever is driven to a vertical position, the IC package can be easily pulled out from the socket connector.
But this type of the socket connector has a potential disadvantage during the lever is driven to the vertical position. A user is not sure whether the socket connector is in the-open state or not, resulting in damage of the conductive pins of the IC package and the socket connector when the package is pulled out in a condition that the cover is non-completely opening.
Hence, a new design which can protect the conductive pins of an IC package and a socket connector is required.
Accordingly, an object of the present invention is to provide an electrical connector with lever-engaging member to sure the lever to be in a complete opening state.
In order to achieve the object set forth, An electrical connector includes a frame defining a substantially rectangular configuration and header and rear portions, a cover moveably disposed on the frame and including a supporting surface with a plurality of holes defined therein, a lever having a cam portion disposed on the rear portion of the frame to drive the cover to move from a first position to a second position, a base disposed within the frame and under the cover and an engaging member retained in one side of the frame. The engaging member defines an engaging portion at one end thereof which can engage with the lever when the lever arrives at a vertical position relative to the base.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
Reference will now be made to the drawing figures to describe a preferred embodiment of the present invention in detail.
The lever 4 is an L-shaped and includes a handle 41 and a cam portion 42 joined with each other at a right angle. The cam portion 42 defines a pair of rollers 421. In assembly, the cam portion 42 of the lever 4 is received in the first channel 221 with the free end retained into the through hole 223, and the rollers 421 are received in the corresponding communicating recesses 224, as the best shown in
In assembly, the cover 3 is retained on the frame 2 with the protrusions 331 defined in a pair of sidewalls 33 retained in the corresponding recesses 24 defined in the frame 2. The cam portion 42 of the lever 4 is received in the first and second channel. The protrusions 331 are movably retained in the corresponding recesses 24 so that the cover 3 can move in a front-to-back direction relative to the base 1. The recesses 24 further can prevent the protrusions 331 from being off in the vertical direction.
The pins will mechanically and electrically engage with the terminals received in the base 1 when the handle 41 is in a horizontal position relative to the base 1. During the handle 41 is turned from the horizontal position to a vertical position, the cam portion 42 with the rollers 421 drives the cover 3 to move in a front-to-back direction, the cover 3 moves from a first position to a second position, and the pins are driven from contacting with the terminals. The handle 41 will pass and engage with the engaging portion 63 when the handle 41 arrives at the vertical position, and the users will fell and know that the electrical connector is in the complete-open state. What's more, the handle 41 is retained between the engaging portion 63 and the blocking portion 53 by the engaging portion 63, and the IC package is easy to pull out of the electrical connector and is unlike to damage the pins thereof.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
